Celio

The Celio, also known as the Caelian Hill, is one of the Seven Hills of Rome.

History
Named for Caelius Vibena, it's unclear whether he received the honor for settling the hill or if his friend Servius Tullius merely wanted to commemorate him posthumously. Either way, as one of the Seven Hills of Rome, Celio was a fashionable residential district for the wealthy during the Republican era of Rome.
